Alex Oxlade-Chamberlain has been added to Liverpool's Champions League squad for the knockout phase.
The England midfielder has not played this season since sustaining serious knee ligament damage in the semifinals of the 2017-18 competition.
He has been added to the final 25-man group for the last-16 onwards, though, along with 17-year-old Ki-Jana Hoever and Ben Woodburn, who is on the B list.
Juventus has chosen to drop Juan Cuadrado, meanwhile, with the winger recovering from an operation on his left knee in December.
Barcelona has added B-team forward Moussa Wague to its squad, along with new signings Jeison Murillo and Kevin-Prince Boateng.
Alvaro Morata is in the Atletico Madrid squad as expected, while Real Madrid has added Brahim Diaz, who joined from Manchester City last month.
City has named Claudio Bravo on its list, with Eliaquim Mangala dropping out.
All last-16 contenders were permitted to register a maximum of three new A-list players for the last 16 before the deadline of 0000CET last Saturday.
